Description
Technical field
The utility model relates to automotive engine component, particularly a kind of door in electrojet solar terms.
Background technique
The throttle body of domestic low and middle-grade automobile electronic fuel oil jet oil-fired systems is mainly mechanical type air throttle body at present, its gas handling system is mainly to drive swing frame to rotate by controlling the motion of acceleration cable, throttle plate pin and throttle blade are rotated, and by position transducer, the aperture signal of throttle blade is exported to automobile electronic fuel oil jet system central unit (ECU).ECU is according to vehicle working condition and sensor signal, and the oil spout of prompting oil sprayer, makes gasoline and air be able to abundant mixing, reaches best chemically correct fuel, and gasoline is fully burnt, the content of the toxic gas such as CO and oxynitrides in vehicle exhaust while reducing idling operation.When engine start, idling operation, ECU controls the stepper motor be arranged on body and rotates, and adjusts the aperture of by-pass on throttle body, the air inlet with control engine when each operating mode.
Throttle body is the key components and parts of control engine air inlet in automobile fuel injection system, after existing throttle body in use exists torsion spring to occur extremely, make accurately return clamping stagnation even of throttle blade, or because of the mounting point precision offset of torsion spring on throttle plate pin, cause equally the accurately problem of return of throttle blade.
Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of torsion spring functional reliability the high door in electrojet solar terms with guaranteeing the accurate return of throttle blade.
The purpose of this utility model is achieved through the following technical solutions: a kind of door in electrojet solar terms, it comprises body, be arranged on the throttle plate pin of body interior, be arranged on the throttle blade on throttle plate pin, be arranged on the swing frame assembly of throttle plate pin one end, the stepper motor that is arranged on body and is connected with the throttle plate pin the other end, be arranged on the torsion spring between body and swing frame assembly and be arranged on the stop screw on body, it also comprises axle sleeve, axle sleeve is arranged on the throttle plate pin between body and swing frame assembly, torsion spring set is contained on axle sleeve, torsion spring is torsion spring, one end of torsion spring is fixed on body, the other end of torsion spring is fixed on swing frame assembly, the bottom surface of body is provided with intake manifold junction surface.
Described throttle plate pin is spacing and be fixed on body interior by collar, in the gapped draw-in groove being fastened on throttle plate pin of collar.
Described inner body wall is provided with all-in-one-piece by-pass and the air inlet by-pass of giving vent to anger.
On described body, be provided with sensor.
The utlity model has following advantage:
1, adopt torsion spring, be conducive to improve the return performance of throttle body in throttle body assembly, idle stability, thus reduce motor vehicle exhaust emission, improve driving safety.Adopt torsion spring to replace single torsion spring, and torsion spring warp beam sleeve is arranged on throttle plate pin, guarantee the unlikely generation skew of torsion spring position on throttle plate pin and produced displacement, make accurately return of throttle plate pin, guarantee the normal operation of motor, axle sleeve can reduce the friction between torsion spring and body in addition, and the long torsion spring life-span of the court of a feudal ruler is improved the reliability of closure.In addition,, after wherein a torsion spring occurs extremely, another root torsion spring can play a protective role in a short time, thereby has improved driving safety.
2, this novel body air inlet by-pass adopts monolithic construction, and profile is more compact, attractive in appearance, saving material, and middle part, body main passage (throttle blade aperture scope) adopts stretched design, and body wall thickness is even, and structural strength is better, and beautiful shape; And the anterior internal channel of throttle blade is up big and down small taper, intake efficiency is high.
3, adopt bidirectionally limited structure, can effectively control axial float, prevent that closure is because of axial float hair fastener.
4, throttle blade adopts aluminium, reduces costs, and reduces the friction between metal.
